About Us

Walgreens is dedicated to providing value in healthcare on a national scale.

We established the Walgreens Center for Health & Wellbeing Research to share our progress and collaborate with our health care partners across a broad range of topics.

This initiative leverages the breadth of our assets: 8,100+ retail pharmacies, approximately 400 retail health clinics, specialty pharmacy programs for patients on complex medication regimes, and our Balance Rewards for healthy choices® program. To measure the impact of our programs, we utilize the talents of more than 25 experienced health services researchers, data scientists, clinicians, statisticians, actuaries and business partners.

We're proud to partner with academic institutions on this journey, including Johns Hopkins Medicine, Scripps Translational Science Institute, the School of Pharmacy at the University of California, San Francisco, and the University of Chicago Medicine & Biological Sciences.
